Title: Chinese character display pager
Inventor: KAN SUSANNA K
IPC: H04W88/02
Filed: 1988-07-06
Granted: 1993-01-26
Abstract: A display device for displaying alphanumeric and/or pictographic characters such as of an Oriental language including Chinese, Korean and Thai and/or graphic information.  The device includes radio receiving circuitry for receiving a radio message in which is encoded characters and/or graphic images to be displayed and at least one display for displaying the received message as characters and/or as a graphic image.  Processing circuitry is adopted to receive the radio message as N-bit message data words from the receiving circuitry, and to convert the data words into displayed characters and/or graphic images in a manner such as to extend the total number of displayable characters and/or graphic images beyond 2N (2 raised to the power N) by using at least one of the 2N possible data words to alter the conversion used to generate the characters and/or usage.  The device includes circuitry for storing the value of at least one parameter used by circuitry of the device for defining a characteristic of its operation and circuitry responsive to at least one command encoded in a received message to set out at least one such parameter to a required value.  Among the parameters which may be set in this way is the identification code of the device.

Title: Method and apparatus for grading fiber suspension
Inventor: VIKIOE PENTTI
IPC: D21D5/18
Filed: 1988-08-31
Granted: 1993-05-25
Abstract: Abstract The present invention relates to a method and apparatus for grading fiber suspension.  The invention especially relates to so called cyclone separators, by means of which particles heavier than the fibers, such as sand and metal particles, are separated from the fiber suspension in the pulp and paper industry.      Prior art apparatus problems include the wearing effect on the conical part caused by the heavier particles remaining rotating in the conical part and the acceptable fraction being allowed to the reject, which fraction the apparatuses of the prior art technique have not been able to return to the pulp circulation during the same separation stage and which thus fills the reject section, whereby the separation of the heavier particles also stops.      The apparatus according to the invention is characterized in that the reject is removed from the cyclone separator (1) to a reject chamber (10),  inside of which a rotor (11)  rotates  maintaining  the pulp  in movement  and efficiently separating the acceptable pulp flowing into the reject chamber (10) from the heavier reject, whereby the acceptable material can be returned back to the pulp circulation along duct (12).  Additionally,  ribs may be provided on the walls of the reject chamber  (10)  to decelerate the rotational speed of the reject, in other words the heavier particles thrown against the wall of the reject chamber have their descent to the bottom of the reject chamber (10) facilitated thereby,  from where they are discharged via a duct (14).     (Fig. 1)

Abstract: ABSTRACT OF THE DISCLOSURE           A method of forming an electric heater pad having a continuous resistance heater wire which zig-zags transversely back and forth in longitudinally spaced runs secured intermediate two insulating sheets, the method comprising:          (a) laying the wire inbetween the sheets by successive passes back and forth transversely between the sheets, (b) drawing the two sheets with the wire therebetween between two first pressure rollers to bond central areas of the sheets together leaving border strips on each transverse slide edge of the sheets unbonded, and (c) subsequently, bonding the sheets together over the border strips, wherein each successive pass comprises:  (1) catching the wire between the sheets in a nip between the first rollers near the juncture of the border strips and central areas at one side, (2) drawing the wire transversely across the sheets to beyond the side edges of the sheets at the other side where tension is applied to the wire forming it into a straight run extending transversely across the sheets so that the straight run is promptly caught in the nip and secured between the sheets over said central areas, and (3) wherein before the step (1) of catching the wire in the next following pass, drawing portions of the wire which have been drawn out beyond the side edges of the sheet at the other side back transversely inward of the side edges of the sheet.  This method ensures the wires are straight and properly spaced.

Granted: 1992-02-11
Abstract: ABSTRACT        An energy efficient scale using a load cell for weight detection and a power supply for powering the load cell at one or another of three different current levels. The highest current level provides accurate weight indication,  The intermediate current level provides only a signal indicating the presence of a package on the scale.  The lowest current level is sufficient only for keeping the load cell electrically centered.  If a package is placed on the scale while the load cell is receiving current at the intermediate level, then a resulting package detection signal causes the scale to switch to full operating current.

Title: Multi-stage wideband successive detection logarithmic amplifier

IPC: G06G7/24

Granted: 1991-12-17
Abstract: PATENTS     ABSTRACT OF THE DISCLOSUREYTY      A successive detection logarithmic amplifier consists of multiple stages, with each stage containing a field-effect transistor (FET) which functions a both an amplified and a detector.  The FET, having an external gate biasing terminal, is biased to operate in its linear region as an amplifier. The gate-source junction of the FET, which is a diode, functions as the detector.  When a signal exceeding a predetermined threshold is applied to the FET, the gate-source junction conducts current in the forward direction during the positive half-cycles of the input signal.  During the negative half-cycles of the input signal, very little current flows through the gate-source diode junction.  The time average of the forward current peaks produces a voltage across a resistor connected between the external gate bias terminal and ground. The voltage at the external gate bias terminals of each of the stages are summed to form a video output signal, a piece-wise linear voltage which is logarithmically proportional to the input signal at the initial stage.

Abstract: A B S T R A C T An arrangement and method for providing an elongated light source, such as for illuminating a sign or the like or. for other display, which includes emitting light from an exterior light source into an inner tube having a portion lined with a high reflectance film of prismatic lenses, the tube having a light-transition opening along its length, with a diffusing medium substantially diametrically opposite such opening, and optionally a reflector at one end of the inner tube. The inner tube is concentrically surrounded by an outer tube having light-transmissive portions of different colors. The outer tube is rotatable relative to the inner tube. The emitted light propagates in the inner tube by reflecting from the high reflectance lining and the reflector to impinge on the. diffusing medium and thereby transmit light outwardly through the light-transmissive opening and thereafter through a selected one of the colored portions so as to project colored light against a sign or like object. The arrangement and method may be used as a color display, for both ambient-light and internal illumination, by interspersing the light-transmis-sive portions with opaque portions of substantially the same color. Several units may be placed end to end to provide a color-code display.
